I have the Jc5 for about a month now and the darn thing is still breaking in! Now having said that, this is just a first rate amp period! Out the box , I questioned the whole upgrade process, two weeks later I started upgrading everything around it cables,dac etc.. (JCP 2 bypass is being saved for as we speak) The integrity of the soundstage is so solid on a three dimensional axis., images are palpable, musical timing and flow can produce goose bump city. Volume be it low level listening or cutting loose the music just remains stable and no hint of dynamic compression just unbelievable. I"m so glad I went all in on the Jc5!
